The Happy Hippopotami: 05/12/12
The Happy Hippopotami by Bill Martin Jr. is about a family of hippos going to the beach for a picnic. They have numerous misadventures over the course of the day, all of which is set to rhyme.
The illustrations aren't done by Eric Carle. Without his collages it just doesn't seem like a Bill Martin Jr. book. I realize that's a silly way to think but the two work so well together.
The book is meant to be read aloud but the forced rhymes tripped me up in a bunch of places. If you plan to read this book to a group of children, I recommend practicing a few times before doing it live.
